ISO/IEC 27001 formally specifies a management system that is intended to bring information security under explicit management control. Being a formal specification means that it mandates specific requirements. Organizations that claim to have adopted ISO/IEC 27001 can therefore be formally audited and certified compliant with the standard (more below).
The standard contains 11 domains(apart from introductory sections)
- Security policy - management direction
- Organization of information security - governance of information security
- Asset management - inventory and classification of information assets
- Human resources security - security aspects for employees joining, moving and leaving an organisation
- Physical and environmental security - protection of the computer facilities
- Communications and operations management - management of technical security controls in systems and networks
- Access control - restriction of access rights to networks, systems, applications, functions and data
- Information systems acquisition, development and maintenance - building security into applications
- Information security incident management - anticipating and responding appropriately to information security breaches
- Business continuity management - protecting, maintaining and recovering business-critical processes and systems
- Compliance - ensuring conformance with information security policies, standards, laws and regulations
